Question

1.Consider the following program written in C syntax:

void fun (int first, int second) {
first += first;
second += second;
}

void main() {
int list[2] = {1, 3};
fun(list[0], list[1]);
}

If the fun subprogram uses "pass by value" parameter-passing method, what are the values of the int array "list" after the call to fun within main?

list = {1, 1}

list = {1, 3}

list = {3, 3}

list = {2, 6}

2. Consider the following program written in C syntax:

void fun (int first, int second) {
first += first;
second += second;
}

void main() {
  int list[2] = {1, 3};
fun(list[0], list[1]);
}

If the fun subprogram uses "pass by reference" parameter-passing method, what are the values of the int array "list" after the call to fun within main?

list = {1,1}

list = {1,3}

{list = {3,3}

list = {2,6}

list = {1, 1}

list = {1, 3}

list = {3, 3}

list = {2, 6}
